Definitions
- the present invention relates to an interchangeable capsule to prepare an infusion of a powdered product, for example coffee or similar products.
- the present invention also relates to a method for obtaining an infusion of said powdered product.
- the present invention is directed to prepare the so-called "American coffee”.
- the present invention has advantageous but not exclusive application to the interchangeable capsules to prepare an infusion of "American coffee” (to which the following description will make explicit reference without loss of generality), the teachings of the present invention may be applied to any type of interchangeable capsule for example to the interchangeable capsules for espresso coffee, tea, chamomile etc..
- American coffee is an infusion obtained by the use of a particular machine wherein the hot water passes through a filter containing the grounded, un-pressed coffee and is deposited by gravity into an underlying carafe.
- the coffee that is used to prepare said beverage differs from that used in "moka” machines or Italian espresso by the fact of being coarsely ground and not being subjected to any precompression when arranged inside the capsule.

Description
- The present invention relates to an interchangeable capsule to prepare an infusion of a powdered product, for example coffee or similar products.
- The present invention also relates to a method for obtaining an infusion of said powdered product.
- In particular, the present invention is directed to prepare the so-called "American coffee".
- Incidentally, although the present invention has advantageous but not exclusive application to the interchangeable capsules to prepare an infusion of "American coffee" (to which the following description will make explicit reference without loss of generality), the teachings of the present invention may be applied to any type of interchangeable capsule for example to the interchangeable capsules for espresso coffee, tea, chamomile etc..
- As known, being defined as "American coffee" is an infusion obtained by the use of a particular machine wherein the hot water passes through a filter containing the grounded, un-pressed coffee and is deposited by gravity into an underlying carafe.
- The coffee that is used to prepare said beverage differs from that used in "moka" machines or Italian espresso by the fact of being coarsely ground and not being subjected to any precompression when arranged inside the capsule.
- Coffee maker machines specially made to prepare American coffee and characterized by a very simple operation are commercially available.
- In fact, these machines comprise a water tank, a pump that sends the heated water inside a small container provided with a paper filter containing the coffee. The hot water submerges the coffee and, passing through the paper filter, falls by gravity into the underlying carafe suited to keep the drink hot for a long time as it is heated by a suitable electrical resistance element.
- In addition to the traditional American coffee makers wherein the cup-shaped filter is filled manually by the user, capsules which have an outer casing wherein a paper filter partly filled with un-pressed coffee is inserted have recently appeared on the market.
- By means of specialized percolator machines the lid and the bottom in plastic material are perforated so as to create a flow of hot water allowing an infusion of the coffee powder.
- However, the capsules currently on the market do not work reliably. In fact normally only providing a filter on the bottom, the incoming hot water is induced to flow along substantially vertical preferential fluid threads and therefore does not affect the entire mass of the powdered product contained inside the capsule.
- It is also known, by
US 2013/156897 A1 orUS 2006/065127 A1 orUS 2011/274802 A1 , to provide a capsule comprising a bottom deflector or lateral ribs so as to affect the circulation of the infusion and improve the quality of the "American coffee". However these known capsules have the disadvantage that the quality of the infusion is still not maximized. - Therefore, the main purpose of the present invention is to provide an interchangeable infusion capsule wherein the infusion water path within the capsule itself is as extended and tortuous as possible to delay the infusion time and to affect a greater quantity of product as possible.
- Further object of the present invention is to provide an innovative method for obtaining said infusion.
- According to the present invention, therefore, a interchangeable capsule is obtained, as claimed in claim 1 or in any of the claims depending directly or indirectly on claim 1.
- Always in accordance to the principles of the present invention, is provided an innovative method for obtaining an infusion of a powdered product, as claimed in claim 13 or in any of the claims depending directly or indirectly on claim 13.

Preferably, thebasket 94 is made of non-woven fabric; alternatively, thebasket 94 is made of plastic material for food use and has a plurality of micro slits for filtering the infusion. Preferably, thebasket 94 is made of a deformable material. - The
basket 94 is fixed inside thecapsule 90 by means of the interaction between the cup-shaped body 101 and thelid 102 and rests on thebottom 101A of the cup-shaped body 101, as will be better explained later. Thecapsule 90 comprises, finally, abase 100 defined by a disc of rigid material with a circular profile. Preferably, thebottom cover 100 is made of plastic material suitable for food use.

shaped body 101 comprises, in turn, abottom 101A obtained advantageously, but not necessarily, in one piece with alateral wall 101B. - Note that through the
bottom 101A an axis (X) passes, that lies substantially on a plane (n) which defines a substantially horizontal direction. - Furthermore, in the present context any "substantially horizontal" body element or device is a body element or device that lies substantially on the plane (n). It must obviously be considered as "substantially horizontal" also body elements or devices which lie substantially on any plane parallel to the plane (n).
- As shown in the figures, the longitudinal axis (Y) is a central vertical axis of symmetry perpendicular to said axis (X).
- So, in the present context any body element or device "substantially vertical" is a body element or device that substantially extends according to the direction defined by the axis (Y).

lateral wall 101B has the usual substantially frusto-conical countersunk shape along the axis (Y). - The cup-
shaped body 101 has anupper end 103 and comprises acontact edge 104 in the shape of a circular crown which protrudes radially outside thelateral wall 101B to ensure that the entireinterchangeable capsule 90 can be housed in an appropriate receptacle obtained in a percolator machine (not shown). The supportingedge 104 also has acircular recess 104A obtained along the entire inner circular perimeter of thecontact edge 104 itself. Therecess 104A is facing inside thecavity 91. - The cup-
shaped body 101 comprises, furthermore, aring 111 coaxial with the axis (Y) and which axially protrudes from thebottom 101A outside of the cup-shaped body 101 itself. Thering 111 is suited to form a watertight sealing area in contact with a contact base of thecapsule 90. - Preferably, but not necessarily, the
bottom 101A, thelateral wall 101B, thecontact edge 104 and thering 111 are made in one piece with a suitable, known type plastic material for food use. - The cup-
shaped body 101 also comprises a plurality ofribs 105 that protrude longitudinally to thelateral wall 101B and within thecavity 91. Theribs 105 are evenly distributed around the axis (Y). Twoadjacent ribs 105 of the cup-shaped body 101 define arespective infusion channel 106.

shaped body 101 comprises, furthermore, a plurality ofsupport elements 107, which protrude from thebottom 101A inside thecavity 91. As shown in the figures, thelower opening 93 is concentric with the axis (Y) and thesupport elements 107 are evenly distributed around saidlower opening 93. - The
support elements 107 form a labyrinth path. In particular, thesupport elements 107 are divided into radial walls 107A and curved walls 107B. The radial walls 107A are interposed between the curved walls 107B and the opening 93. As shown inFigure 2 , the curved walls 107B are evenly distributed around the longitudinal axis (Y) and are formed as portions of a cylindrical body. Preferably the walls 107B are four and each curved wall 107B has a central angle of about 80°. The radial walls 107A are evenly distributed around the longitudinal axis (Y). Preferably the radial walls 107A are fourteen. - As a result from what has just been described, each
support element 107 is spaced from anothersupport element 107, so that on the bottom of the cup-shaped body 101 a labyrinth path arranged radially around thelower opening 93 is formed. - As illustrated in

Thebottom cover 100 is fixed to the bottom 96 of thebasket 94 by way of known methods (hence thebottom cover 100 is fixed by means of thebasket 94 also to the support elements 107); for example, thebottom cover 100 is welded or glued to the bottom of thebasket 94. - According to a variant not illustrated, the
bottom cover 100 is fixed to the bottom 96 of thebasket 94 and to the outside of thecavity 97. According to a further variant, not illustrated, thebasket 94 has a tubular shape and thebottom cover 100 is arranged to close said tubular shape acting substantially as a bottom for thebasket 94. According to a further variant, not illustrated, thebottom cover 100 is fixed, for example welded or glued, onto thesupport elements 107. - The
lid 102 is arranged within theupper opening 92 and is coaxial with the longitudinal axis (Y). Thelid 102 is supported within therecess 104A and on theedge 99. Preferably, thelid 102 is welded to theedge 104 of the cup shapedbody 101 at therecess 104A. Preferably, thelid 102 is mounted with interference inside theedge 104 of the cup-shapedbody 101 so as to hold theedge 99 of thebasket 94 against the cup-shapedbody 101 itself. - In
Figures 3 and 4 an alternative 101' of the cup-shapedbody 101 is illustrated, it is noted that infigures 3 and 4 the elements in common with the cup-shapedbody 101 maintain the same numbering. The cup-shaped body 101' comprises a plurality of support elements 107', which protrude from the bottom 96 inside the cup-shapedbody 101 itself. The support elements 107' are arranged radially around the axis (Y). The support elements 107' form a labyrinth path. The support elements 107' are divided into bars of larger dimensions 107'A and into bars of smaller dimensions 107'B. Two adjacent bars of smaller dimensions 107'B are interspersed with a bar of larger dimensions 107'A. - The different arrangements of the
support elements 107 or 107' on the bottom 96 of the cup-shapedbody 101 or 101' are suited to maximize the outflow and the quality of the infusion. - Preferably, the cup-shaped
body 101, 101' and/or thebasket 94 and/or thelid 102 are made of biodegradable material. - The operation of the
present capsule 90 is the following: - a) Pressurized or percolated hot water in the cup-shaped
body 101, 101' is introduced through the hole 108 (possibly by breaking thefilter 109 if made of plastic material) according to the direction and the way identified by the arrow (F1); - b) the hot water after passing the
filter 109 immediately meets the powdered product arranged in thecavity 97 of thebasket 94 and the produced infusion liquid/hot water begins to form; - c) said infusion liquid impacts the bottom 100 and is deflected horizontally and radially according to the directions and the ways of the arrows (F2);
- d) the infusion liquid is pushed through the
lateral walls 95 and outside thebasket 94; - e) the
lateral wall 95 of thebasket 94 is deformed under the action of water pressure and against theribs 105 of the cup-shapedbody 101 so to have a substantially curvilinear trend with an alternation oflongitudinal protrusions 110 protruding inside thecavity 97, as will be better explained in the following; - f) the infusion liquid colliding with the
lateral walls 101B of the cup-shapedbody 101, 101' is channeled within thechannels 106 between theribs 105; - g) the infusion liquid flows along the
channels 106 towards the bottom 101A of the cup-shapedbody 101, 101' in the direction (F3); and - h) the infusion liquid flows radially in the direction (F4) on the bottom 101A towards the
opening 93 and then is distributed to the outside of thecapsule 90; flowing on thebottom 101A the infusion fluid passes through the labyrinth path created by thesupport elements 107, 107'. - In particular, each
protrusion 110 is made so as to be arranged at least partially around arespective rib 105. - Preferably, each
protrusion 110 is tapered in the vicinity of both ends. In particular, eachprotrusion 110 has a substantially trapezoidal cross-section the size of which varies along the axis (Y). Preferably each protrusion has a radial extension along thelateral wall 95 in correspondence of the lower longitudinal ends and increased in correspondence to a central area. Preferably the trapezoidal profiles of twoadjacent protrusions 110 are in contact with each other in the vicinity of a substantially central area. Eachprotrusion 110 is suited to wrap, at least partially, arespective rib 105, as will be better explained in the following. - After the delivery of the infusion the cup-shaped
body 101, 101' can be tightened below theedge 104 so as to cause a plastic deformation in the cup-shapedbody 101, 101' itself, and to allow to extract thelid 102. In this way it is possible to clean up (for example by emptying and rinsing) thebasket 94 and separate the plastic material from the organic material so as to facilitate the recycling and separate collection of all the components of thecapsule 90. - From the above description, the
bottom cover 100 is transverse to the direction F1 of the liquid inserted in thebasket 94 so as to divert the direction horizontally. Thebasket 94 basically acts as a filtering means wherein thelateral wall 95 is suited to filter the infusion created by the mixing of water and powdered product. - The present invention also relates to a method for the production of a beverage infusion in particular of American coffee; the method is characterized by the following steps:
- (f1) centrally and vertically injecting a given amount of hot water into the
basket 94; - (f2) causing at least part of the hot water to be deflected in a substantially horizontal direction by the
deflector device 100; - (f3) deforming the
lateral wall 95 of thebasket 94 by means of the interaction of the hot water and of the spacer elements, such as theribs 105; - (f4) filtering the infusion in said substantially horizontal direction causing it to pass through substantially vertical filtering means 95; 110 of the
basket 94 so as to convey said filtered infusion inpreferential channels 106 created between the cup-shapedbody 90 and thebasket 94; - (f5) converging the filtered infusion along said
preferential channels 106 towards the bottom 101A of the cup shapedbody 101; 101'; and - (f6) mixing the filtered infusion by means of the
support elements 107; 107' before the outflow of the filtered infusion itself from thecapsule 90 through theopening 93 on the bottom 101A of said cup-shapedbody 101; 101'. - The advantages of the capsule object of the present invention are the following:
- the
capsule 90 of the invention has preferably, but not necessarily, ahole 108 from which the first entry of the hot water from a jet of the machine takes place; the hot water is thus evenly distributed in the mass of powdered product contained inside thebasket 94; this feature allows to control in a uniform and constant way the distribution of water in thecapsule 90 itself; - the bottom of the
basket 94 is closed to prevent preferential vertical outflows of water in the infusion step, as instead happens for the other known capsules on the market having a filter on the bottom or a single opening created due to a puncture of the bottom itself; - the filtering area of the infusion is substantially vertical through the
lateral walls 95 of thebasket 94 so as to have a larger filtration area with respect to the capsules providing a coffee filter arranged only on the bottom; furthermore, this vertical filtering creates a turbulence effect improving the exploitation of the product to be infused; - with the
capsule 90 it is possible, in the industrialization step, to perform central dosing thus simplifying the implementation of the machinery responsible for the packaging of the same; - the
ribs 105 maintain thelateral wall 95 of thebasket 94 spaced from thelateral wall 101B of the cup-shapedbody 101, 101' preventing the two to adhere (in this case the infusion liquid would not be able to flow out in the direction (F3) outside the basket 94); - the
ribs 105 together with thelateral wall 95 of thebasket 94 delimit a plurality ofpreferential channels 106 which allow the outflow of the infusion liquid and allow particularly advantageous timing and constant dispensing; in particular, it is to be noted that the shape and the size of eachpreferential channel 106 is definable by the suitable dimensioning of theribs 105, so as to obtain the best possible quality of fluid infusion given by obtaining both the optimal pressure and speed of the outflow; - the
protrusions 110 increase the filtration area being equal the total radial dimensions of thecapsule 90; and - the particular distribution of the
support elements 107 on the bottom 101A allows to create a tortuous path of the filtrated infusion liquid thus improving the quality, in particular, allowing a greater extractive capacity of the infusion; moreover, the path of thesupport elements 107 affects the outflow of the filtrated infusion liquid along saidpreferential channels 106; - the possibility to easily disassemble the
lid 102 and thebasket 94 from the cup-shapedbody 101, 101' enables the total recyclability of all the components of thecapsule 90 being able to differentiate the components, one with respect to the other, according to the type of waste (plastic-organic); moreover, in this way it is also possible to reuse multiple times the cup-shapedbody 101, 101' and thelid 102 only substituting the basket 94 (reduction of waste).
